It is obviously true that none of us would be here today were it not for our association with Jonathan. But I can honestly say that I would not be here as Columbia music professor were it not for him. When I was an undergraduate at Yale in the early 1970s, Jonathan was a young assistant professor of composition there, and I took several courses with him, including ones on Stravinsky and Orchestration. I felt a strong rapport with him, and when I was considering applying to graduate study in musicology, it was natural that I would consult him. I remember, after having left Yale, coming to stay with him and Norma and the kids at their house, as he generously offered advice about my graduate study. He had studied at Berkeley, and had worked there with Joseph Kerman. Because Jonathan knew of my interest in criticism and critically oriented musicology, he recommended Berkeley most strongly. And I followed his suggestion. I recall writing to Jonathan (by snail mail, of course, in those days) during my years in California, updating him on my studies; he always responded warmly. By then, Jonathan was teaching in Cincinnati, and we didn't have that much contact over the next number of years, until in the mid 1980s Columbia announced a search for a senior music theorist. I remember Jonathan calling me and asking about the position and whether he should apply. I said yes, yes! Of course, he did come to Columbia and helped form the Theory program. We became colleagues. But his generous mentorship of me was not completed. When I was being evaluated for promotion to tenure in 1989-90, Jonathan supported me and volunteered to be the "expert witness" at the ad hoc tenure committee meeting. I remember having coffee with him, at his suggestion, at Chock Full o' Nuts at Broadway and 116th (that dates us!), as he asked me how I felt he could best make the case to the committee. This was typical of his kindness and advocacy. He did make the case, I received tenure in 1990 and--largely thanks to his efforts on my behalf dating back to my undergraduate days--had the privilege of being Jonathan's colleague for another 14 years. That I am here speaking at his funeral is at once unimaginable to me and thoroughly appropriate.
